Overview:

The NPort® W2150A and W2250A are the ideal choice for connecting your serial or Ethernet devices, such as PLCs, meters, and sensors, to a wireless LAN. Your communications software will be able to access the serial devices from anywhere over a wireless LAN. Moreover, the wireless device servers require fewer cables and are ideal for applications that involve difficult wiring situations. In Infrastructure Mode or Ad-Hoc Mode, the NPort® W2150A and NPort® W2250A can connect to Wi-Fi networks at offices and factories to allow users to move, or “roam,” between several APs (Access Points), and offer an excellent solution for devices that are frequently moved from place to place.

 

802.11a/b/g/n Wireless Connectivity to Serial Devices:

Wireless device servers require fewer cables and are ideal for applications that involve difficult wiring situations. In Infrastructure Mode or Ad-Hoc Mode, the NPort® W2150A and NPort® W2250A can communicate with any host computer through an access point, or with another NPort® W2150A or NPort® W2250A located up to 100 meters away.

 

Wireless Fast Roaming Function:

Wi-Fi networks at offices and factories allow users to move, or “roam,” between several APs (Access Points). Moxa’s Fast Roaming function increases the roaming speed to unify AP channels and avoid wasting channel hopping time while roaming.

 

Wireless Client:

Data can be seamlessly transferred between the serial line, LAN, and WAN, allowing the LAN and WLAN interfaces to be bridged together with one IP address.

 

Offline Port Buffering and Serial Data Log for Each Port:

For mission-critical applications, data from the serial device must not be lost if the wireless connection goes down. The NPort® W2150A and NPort® W2250A are designed to continue operating if the wireless connection is disconnected temporarily. If the wireless connection is restraining, or if the connection fails, the serial data from the serial device will be queued in the built-in port buffer with over 10 MB of storage. As soon as the wireless connection returns to normal, the data stored in the buffer will be sent to its destination. In addition, a serial data log can be enabled to make troubleshooting easier.

 

The serial data log buffer for both the NPort® W2150A and NPort® W2250A is 64 KB per port.

 

Secure Remote Management and Configuration with SSH/HTTPS:

Unauthorized access is one of the biggest headaches for system managers. In addition to IP filtering and password protection, the NPort® W2150A and NPort® W2250A also support SSH and HTTPS to provide protection from hackers. To transmit control messages securely, open the web console using a web browser that supports https (Internet Explorer, for example). You may also open the serial or Telnet console, such as PuTTY, using a terminal emulator that supports SSH.

 

Select “Any Baudrate” between 50 bps and 921.6 kbps:

Most device servers only support a fixed number of serial baudrates. However, some applications require special baudrates, such as 250 kbps or 500 kbps. With the NPort® W2150A and NPort® W2250A, you can enter any baudrate between 50 and 921.6 kbps. If your device’s baudrate is not a standard baudrate, select “other” from the drop-down list and then enter the baudrate.
